DELTA 1 DEB, 21496
Orbit data source: Space-Track
DELTA 1 DEB, 21496 is space debris in SSO originally from a launch on Thu, 12 Jun 1975 UTC launched from the Air Force Western Test Range (AFWTR). Debris objects in space refer to the collection of defunct objects orbiting the Earth. Examples of debris include non-operational satellites, rocket bodies, and fragments generated from explosions, collisions, or faulty payload assembly.
